Wish to run the BHP world record train

**derekmorton** · 11-06-2018, 04:29

Just to add, this train had 675 coal wagons.

Hi Derek,

The BHP Iron Ore world record train had 682 (iron) ore cars.

When I select your activity in OR I get a <missing: unknown> locomotive and missing consist au_2d8+104loaded_2rake_mixed_large.

Note that the BHP June 2001 world record train was run with all 8 of the AC6000 locos to demonstrate Locotrol III. This train was assembled at Yandi Junction where a Yandi train was connected to a Newman train. The entire train did not run on the Yandi branch so the only climbing it did was up the Chichester Ranges where the coupler broke.

I have attached the consist file for this train. The AC6000 locomotives are in bhp_ac60.zip and 125 tonne Comeng ore cars are in pilbara_m636_pack.zip which can be downloaded from the file library here.

BHP did have a previous world record in May 1996 with 10 CM40-8M and 540 ore cars and I have included a consist file for that as well.

Cheers,

Marek.

Today a BHP loaded 268 car iron ore train ran away without the driver for approx 50 miles before being deliberately derailed.....bit of a mess all round. https://www.bbc.co.uk/news/world-australia-46105280

Thanks for the corrections Marek.
I was using a consist that I thought came with the install.
I certainly didn't build it.

As I am crashing Goku's editor, I am waiting for a fix.

**frliss** · 11-06-2018, 06:26

Just out of curiosity, I read a news article a few years back that all of BHP's AC6000 were sitting in a dead line with their batteries and oil removed. A year or so after that I heard online that these engines were scraped or sold. Does anyone know the disposition of these engines?

https://www.pilbararailways.com.au/bhp/ac6000.php has the history of these locomotives. 6070 was written off in 2011 following an accident, and the rest were scrapped in October 2014.

With 13 downloads, I expected more people to come back with errors.
Merak has indicated he does not have the consist, so I am at a loss as to where I got it from.

**superheatedsteam** · 11-06-2018, 22:33

Hi Derek,

It's possible (and highly likely) that I have deleted those consists from my installation.

Cheers,

Marek.

Well, coincidentally, I've been running this route for a couple of months. I wanted something extreme to test the files I have been making...just to see how they held up. I have OR conversions for all the stock for the BHP. I used the data/physics exactly as found in Mareks engine files.

I'm having trouble going up to the main line from the Yandi balloon. Cannot seem to make it...my guess is that it's my inexperience. When I run from Mac I do okay. It will be interesting to try to world record consists in OR.

If anyone is interested I can make up a conversion kit and attach it here, or upload to library.
I also have all the Dash9s found in pilbara_c44-9w_kd.zip converted. They are all in one folder so the end user will have to separate them out.

Hi All,

well 12 downloads.

I need feedback on whether you have got it to work?

Hi Derek,

Yes, it works for me, but I think you need to clarify some things.

First, was this activity designed for MSTS or ORTS? The signals and meets on a single-track route such as this will vary between the two sims.

Secondly, if it was designed for ORTS, what optional variables were you using when you did the design work? Depending upon the combination of those the act will play out differently as well. Here's what I've been using:

General tab: Alerter in cab, Retainer valve on all cars and 21 PSI for Brake pipe charging; Graduated release air brakes NOT selected
Simulation tab: Everything checked except Override non-electrified route line-voltage ;-)
Experimental tab: All checked except Automatically tune settings, ETCS circular speed gauge, Signal lite glow and MSTS environments. Adhesion level is Hard

I haven't finished the activity yet because I keep breaking couplers; I'm gradually learning at what point along the route I have to be very gentle â€¦

Thanks for making this activity, as despite the fact that the terrain looks a bit like Mars and there's not much to see, driving this train takes real skill â€¦ which equals a lot of fun!!

Cheers,

David

Hi Gerry,

I have just tested (in OpenRails) the climb out of Yandi 1 from a standing start with the lead loco starting at the turnout of the ballon loop. Using the au_2D8+104loaded_2rake_mixed.con consist that comes with the CM40-8M locos, the train makes it to the crest of the hill MP298 at ~16km/h.

This is slightly slower than it should be because those locos were released for MSTS and MSTS does not calculate parasitic loads on the prime mover for the MaxPower variable, however OpenRails does. I changed the MaxPower value for the CM40-8M locos to MaxPower ( 3132.0kW ) and tested again. This time the minimum climb speed was a bit higher at ~18 km/h, which I believe is still a couple of km/h slower than it should be. I also reached the crest several minutes sooner. I will have to find my notes on this to confirm but I believe the minimum speed up this section was in the order of 19-20 km/h with 104 car rakes.

Also note that the train composition matters. Train compositions on this route have changed over the years but the 2 x CM40-8M locos hauling 104 ore cars weighing 145 tonnes each in a twin or triple rake is what was used to climb the ruling gradient at that time without dropping below minimum continuous speed. Adding or removing a couple of ore cars is going to make a difference when the consists are already optimised.

Hope this helps.

Cheers,

Marek.

Yes, it does, thanks. To clarify, I've attached the ORTS CM40-8 engine include file. I'm using 4100HP - tractive and 4350 as maximal ( or gross ) HP.
Are these figures in alignment with what you use?

I forgot to ask, does anyone have a path from Yandi Junction to the coast?
I do not have the route set up to use any MSTS editors and being consumed by trying to understand physics has left little time to learn the Trackviewer path making function or even beginning to use the TSRE AE function.
Appreciate any help.
